Petunia plant named ‘Petrosve’

ABSTRACT

A new and distinct cultivar of  Petunia  plant named ‘Petrosve’ characterized by its trailing, outwardly spreading and mounded plant habit, freely branching habit, freely flowering habit, single flowers that are rose in color with darker purple-colored venation, and good garden performance.

Latin name of the genus and species of the plant claimed: Petunia hybrida.

Varietal denomination: ‘Petrosve’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct cultivar of Petunia plant botanically known as Petunia hybrida and referred to by the cultivar name ‘Petlavve’.

The new Petunia is the product of a planned breeding program conducted by the inventor in Enkhuizen, Netherlands. The new Petunia cultivar is freely flowering with trailing and spreading habit and attractive leaf and flower coloration.

The new Petunia originated from a cross-pollination made by the inventor in August 1999 of a proprietary selection of Petunia hybrida identified as code number ‘X1041,’ not patented, as the female, or seed parent, with a proprietary selection of Petunia hybrida identified as code number ‘Y1009,’ not patented, as the male, or pollen parent. The new Petunia was selected as a single plant from the resulting progeny of the cross-pollination in a controlled environment in Enkhuizen, Netherlands in June 2000.

Asexual reproduction of the new cultivar by terminal vegetative cuttings since June 2000, in Enkhuizen, Netherlands has shown that the unique features of this new Petunia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar ‘Petrosve’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity and daylength without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Petrosave.’ These characteristics in combination distinguish ‘Petrosve’ as a new and distinct cultivar:

-   -   1. Trailing, outwardly spreading and mounded plant habit     -   2. Freely branching habit     -   3. Freely flowering habit     -   4. Single flowers that are rose in color with darker         purple-colored venation     -   5. Good garden performance

In side-by-side comparisons conducted in Enkhuizen, Netherlands, plants of the new Petunia differed from the plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Petunia had smaller flowers than plants of         the female parent selection.     -   2. Plants of the new Petunia are slightly more mounded than the         plants of the female parent which are upright.

In side-by-side comparisons conducted in Enkhuizen, Netherlands, plants of the new Petunia differed from the plants of the male parent selection in the following characteristic:

-   -   1. Plants of the new Petunia had smaller flowers than plants of         the male parent selection.

Plants of the new Petunia ‘Petrosve’ differed from the plants of the Petunia cultivar Surfinia rose veined (‘Sunrosve’), U.S. Plant Pat. No. 14,125, in plant habit. The plants of the new Petunia are slightly mounded whereas the plants of Surfinia rose veined are more flat.

DESCRIPTION OF THE DRAWING

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Petunia.

DESCRIPTION OF THE NEW CULTIVAR

The observations and measurements describe plants grown in Enkhuizen, The Netherlands., practice circumstances outdoor in windowboxes during the summer with day temperatures ranging from 18 to 25° C. and night temperatures ranging from 10 to 14° C. Plants used for the photographs and description were about 12 weeks from planting rooted cuttings.
